What else can I help you with?
Junction type that allows neighboring cells to exchange small molecules?
Gap junctions allow neighboring cells to exchange small molecules, ions, and electrical signals directly through channels formed by connexin proteins. This enables rapid communication and coordination between cells in tissues such as cardiac muscle and nervous tissue.
Does skeletal muscle have gap junctions?
No. It's the only type of muscle tissue that doesn't have gap junctions. Cardiac and smooth muscles have gap junctions.
What type of membrane junction allows ions to pass directly from cell to cell?
Gap junctions
Which muscle tissue has gap junctions?
Smooth
The type of intercellular junction that forms tubular channels is a?
gap junction
The actual gap between an axon ending and the muscle cell is called what?
Neuromuscular junction.
How would the genetic inheritance of a gene producing abnormal gap junctions effect muscle tissue?
Abnormal gap junctions can impair the ability of muscle cells to communicate effectively, leading to coordination and contractility issues within the muscle tissue. This can result in weakened muscle function, muscle spasms, or even muscle degeneration over time.
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.
Cardiac muscle fibers electrically connect to neighboring fibers by?
intercalated discs, which contain gap junctions that allow for the rapid transmission of electrical impulses between cells. This ensures synchronized contraction of the heart muscle.
What type of junction will hold epithelial tissue?
Epithelial cells are bound together in sheets of tissue called epithelia. These sheets are held together through several types of interactions, including tight junctions, adherens, desmosomes, and gap junctions.
What type muscle cells are arranged in sheets or layers with adjacent muscle cells electrically connected by gap junctions and mechanically connected by dense bodies?
Smooth muscle cells are arranged in sheets or layers with adjacent cells connected by gap junctions and dense bodies. This allows for coordinated contraction and relaxation of muscle tissue.
What does the unique structure of cardiac muscle play in its function?
Cardiac muscle fibres contain GAP JUNCTION in the intercalated disc which makes them to function as a FUNCTIONAL SYNCYTIUM
